Brief · Jobs outlook
Data-center jobs outlook: what is already measurable, and what projections actually say
Data centers do create work for electricians, HVAC techs and pipefitters, but official statistics do not count how many of those jobs come from data centers.
Official industry payroll for hosting / data processing (BLS CES NAICS 518) is real and dated: about 481k in Dec 2024, 473k in Dec 2025, and 454k preliminary in Sep 2026. OEWS May 2025 shows that mix is mostly computer/math and management, not facility trades.
Construction (~8.4M) and specialty-trade contractors (~5.3M) are large nationally and are where many build crews sit. Those CES totals cover all construction and all specialty trade contractors. They are not limited to data-center work.
Future openings for electricians (~72.7k/yr), HVAC/R (~40.6k), pipefitters/plumbers (~42k), and lineworkers (~10.9k) are BLS Employment Projections for the whole economy. No public table publishes a data-center share of those openings, so this page does not give one.
What DataCenterSkilledTrades says this means
- Everyday readers: Big campuses do pull electricians, HVAC, pipefitters, fiber crews and shell trades. Official “data center industry” tables mostly count IT and managers. National construction totals are not a campus headcount.
- Local gov / HOAs: Demand NAICS, employer type, and dated sources for any jobs claim. Refuse invented FTE-per-MW and “X,000 by 2030” without a named filing. Proposal checklist.
- Contractors / GCs / operators: Separate operator 518 payroll from your construction/specialty-trade staffing. Staff by system; treat most certs as a plus unless law requires them. Keep load and water on their briefs.
For everyday readers: two ledgers, one method rule
- Ledger A: official hosting industry: CES NAICS 518 and OEWS 518200. Real, dated, modest relative to power headlines, and mostly not electricians/HVAC/pipefitters. Detail: jobs vs power.
- Ledger B: construction and specialty trades: CES NAICS 23 (~8.4M) and 238 (~5.3M). Real, dated, and where many build crews are coded. Explicitly not data-center-only.
- Method: A suppressed OEWS cell, a national construction total, or an economy-wide openings figure is not a campus FTE count. If someone claims a DC share without a named filing, treat it as unverified.
- Both sides: Hyperscale buildout is big money and pulls real trades (who’s building). The same projects raise local jobs-vs-power, grid, and water questions (jobs vs power, grid load, water).
Jobs already created / measurable employment
What we can say with dated primary sources, and what we must label as non-DC-specific.
Ledger A: NAICS 518 / 518200 (official hosting industry)
- CES NAICS 518 (BLS series CES5051800001): 480.9k (Dec 2024), 472.9k (Dec 2025), 453.8k preliminary (Sep 2026). Seasonally adjusted, thousands of employees.
- OEWS May 2025 NAICS 518200: 485,550 all occupations. Computer and Mathematical 200,900 (41.4%); Management 80,170 (16.5%); Installation/Maintenance/Repair 2,370 (0.5%). Construction and Extraction employment suppressed (**).
- Electricians, HVAC/R, lineworkers, and pipefitters have no published OEWS rows for 518200 in the May 2025 nat4d file. Do not invent them.
Ledger B: construction and specialty trades (NOT data-center-only)
- CES Construction NAICS 23 (CES2000000001): 8,364 thousand preliminary in Sep 2026 (8,276 in Dec 2024; 8,272 in Dec 2025). Label: ALL U.S. construction.
- CES Specialty Trade Contractors NAICS 238 (CES2023800001): 5,279.9 thousand preliminary in Sep 2026. Label: all specialty trades nationally (electrical, HVAC, plumbing, and every other specialty across every building type).
- Related-industry OEWS May 2025 (still not DC-specific): nonresidential building construction (236200): 14,670 electricians and 1,490 HVAC/R; utility system construction (237100): 13,080 electricians and 38,990 lineworkers; electric power (221100): 7,950 electricians and 62,470 lineworkers.

Future projections (published only)
BLS Employment Projections 2025–35 (USDL-26-1422, released 2026-08-27) and the Occupational Outlook Handbook give economy-wide outlooks. Data-center construction adds demand for some of these trades. The CES series do not show how much.
- Electricians (47-2111): ~72,700 openings/yr; employment 821,000 (2025) → 896,900 (2035), +9%. OOH notes AI/data-center electricity demand as a contributor to job opportunities, without a DC FTE count.
- HVAC/R (49-9021): ~40,600 openings/yr; 440,900 → 489,100, +11%.
- Plumbers, pipefitters, and steamfitters (47-2152): ~42,000 openings/yr; 510,600 → 545,200, +7%.
- Electrical power-line installers and repairers (49-9051): ~10,900 openings/yr; 131,900 → 145,500, +10%. OOH likewise names AI/data-center electricity demand as a contributor to grid/infrastructure work.
National OEWS May 2025 wages and employment for those SOCs (all industries) live on /roles/, labeled non-DC-specific. LBNL’s 192 TWh / 4.7% (2024) and EIA commercial shares are power context for why buildout pulls trades (grid-load kit). They are not FTE forecasts.
Trades pulled by data-center buildout
Qualitative map (hire detail on who gets hired and on site):
- Electricians: UPS, switchgear, PDUs, generators, ATS. State license rules vary; NFPA 70E training is a common plus. Many shops hire apprentices and train on the job. NFPA 70E checklist.
- HVAC/R: CRAH/CRAC, chillers, refrigerant side. EPA Section 608 required by law for refrigerant work. EPA 608 guide.
- Plumbers / pipefitters: chilled-water, glycol, CDU facility loops (hydronic / liquid cooling). Liquid cooling guide.
- Fiber / telecom / low-voltage: trunks, splices, patch panels. BICSI INSTF/TECH as a plus; OR LEA / WA 06 where those states license. Many crews hire and train without every BICSI ticket. BICSI INSTF guide · cert checker.
- Concrete / ironworkers / GC shell crews: foundations, slabs, structural steel, envelope. Ordinary commercial construction. We print no crane counts or pour yards.
- Lineworkers: utility feed / transmission-distribution to the substation (utility or utility contractor).
Company buildout context (dated footnotes): home who’s-building · facility-systems strip.
For local governments & HOAs: demand these for every jobs claim
- Which NAICS the claimed jobs sit in (518/518200 operator payroll vs construction 23 / specialty trade 238 / utilities).
- Whether trades are operator employees or GC / specialty-trade / utility contractors coded outside 518.
- A dated primary source (BLS series ID + month/year, or a named local filing) for any headcount.
- An honest “unknown” where OEWS suppresses a cell or where no DC share of construction employment is published.
- Separation of construction-phase jobs from ongoing ops jobs, and no FTE-per-MW invented from LBNL/EIA load figures.
Pair with jobs vs power (load vs 518 payroll), grid-load kit (national load vs local rates), and water kit (consumed vs withdrawn).
For contractors, GCs & operators: do not pad
- Invented campus electrician/HVAC/pipefitter headcounts (OEWS 518200 does not publish those rows).
- Invented FTE-per-MW or 'X,000 data-center jobs by 2030' without a named primary filing.
- Treating CES construction (8.3M+) or specialty trades (5.3M+) as if they were data-center-only.
- Treating CES/OEWS NAICS 518 payroll as if it were mostly facility trades (it is not).
- Using LBNL 192 TWh / 4.7% or EIA commercial shares as if they were FTE forecasts.
Staff bids by system and note which credentials are law vs a plus next to each crew. Failure map: facility systems. Hire matrix: who gets hired.

FAQ
How many data-center jobs have already been created?
The measurable official industry count is BLS CES for NAICS 518 (series CES5051800001): 480.9 thousand in December 2024,472.9 thousand in December 2025, and 453.8 thousand preliminary in September 2026, and OEWS May 2025 for NAICS 518200 at 485,550 all occupations. Those are hosting/data-processing industry payroll counts. They are mostly IT and management, not facility trades, and they are not campus trade staffing plans. Construction and specialty-trade CES totals are much larger nationally, but they cover all construction and all specialty trades, not data centers alone.
Why don't official tables show electricians and HVAC techs inside 'data center' employment?
OEWS May 2025 for NAICS 518200 is IT- and management-heavy: Computer and Mathematical occupations 200,900 (41.4%); Management 80,170 (16.5%); Installation/Maintenance/Repair only 2,370 (0.5%). Construction and Extraction employment is suppressed (**). Electricians (47-2111), HVAC/R (49-9021), lineworkers (49-9051), and pipefitters (47-2152) have no published OEWS rows for 518200. Most facility trades on a build or critical-facility contract work for GCs, specialty-trade contractors, or utilities coded outside 518.
Is U.S. construction employment a data-center jobs number?
No. BLS CES construction (NAICS 23, CES2000000001) was 8,364 thousand preliminary in September 2026. Specialty trade contractors (NAICS 238, CES2023800001) were 5,279.9 thousand preliminary the same month. Those are all construction and all specialty trades nationally. Data-center shell and fit-out work sits somewhere inside those totals. BLS does not publish a data-center share, and this page does not invent one.
What do future projections say about trade demand?
BLS Employment Projections 2025–35 (USDL-26-1422, released 2026-08-27) put average annual openings, economy-wide, all industries, at about 72,700 for electricians, 40,600 for HVAC/R, 42,000 for plumbers/pipefitters/steamfitters, and 10,900 for electrical power-line installers/repairers. Projected employment growth is +9%, +11%, +7%, and +10% respectively. Label these as national trade demand. They are not 'data center jobs by 2030.'
Does BLS say data centers create electrician or lineworker jobs?
BLS Occupational Outlook Handbook profiles for electricians and for electrical power-line installers/repairers state that increasing use of AI technologies and demand for data centers are expected to contribute to rising electricity demand, and that related grid and infrastructure work is expected to create job opportunities for those occupations. That is BLS naming a demand driver. It is not a published count of data-center FTEs, and we do not invent a share.
Which trades does a data-center buildout pull?
Qualitatively: electricians (power path: UPS, switchgear, PDUs, generators), HVAC/R (refrigerant CRAH/chillers: EPA 608), plumbers/pipefitters (hydronic/liquid-cooling facility loops), low-voltage/fiber/telecom installers (BICSI pathway), and concrete/ironworkers plus GC crews for the shell. See /briefs/who-gets-hired/, /briefs/on-site/, and /#whos-building. We print national OEWS wages/employment for those SOCs on /roles/ and label them non-DC-specific.
What should local governments or HOAs demand when a proposal claims jobs?
Ask which NAICS the job claims sit in, whether trades are operator employees or construction/specialty contractors outside 518, and for dated primary sources with month/year. Refuse invented FTE-per-MW, campus trade headcounts, and 'X,000 DC jobs by 2030' without a named filing. Use this brief plus /briefs/jobs-vs-power/, /briefs/grid-load/, /briefs/water/, and /briefs/local-gov-questions/ as briefs.
